7. w/o Driving Position Memory:
INSPECT ELECTRICAL RETRACT MOTOR OPERA-
TION
(a) Driving position:
(1) Connect the positive (+) lead from the battery to ter-
minal 1 and the negative (±) lead to terminal 2.
Check that the mirror moves to the retract position.
(2) Reverse the polarity and check that the mirror does
not operate.
If operation is not as specified, replace the mirror assembly.
(b) Between driving position and retract position:
(1) Connect the positive (+) lead from the battery to ter-
minal 1 and the negative (±) lead to terminal 2.
Check that the mirror moves to the retract position.
(2) Reverse the polarity and check that the mirror
moves to the return position (Stops at the driving
position).
If operation is not as specified, replace the mirror assembly.
(c) Retract position:
(1) Connect the positive (+) lead from the battery to ter-
minal 1 and the negative (±) lead to terminal 2.
Check that the mirror does not operate.
(2) Reverse the polarity and check that the mirror
moves to the return position (Stops at the driving
position).
If operation is not as specified, replace the mirror assembly.
8. w/ Driving Position Memory:
INSPECT ELECTRICAL RETRACT MOTOR OPERA-
TION
(a) Driving position:
(1) Connect the positive (+) lead from the battery to ter-
minal 13 and the negative (±) lead to terminal 14.
Check that the mirror moves to the retract position.
(2) Reverse the polarity and check that the mirror does
not operate.
If operation is not as specified, replace the mirror assembly.

INSPECT ELECTRO CHROMIC INNER MIRROR OPERA-
TION
(a) Cover the sensor A so that the sensor does not receive
any light.
(b) Connect the positive (+) lead the battery to terminal 7 and
the negative (±) lead to terminal 6.
(c) Shine an electric light on the mirror, and check that there
is battery positive voltage and mirror surface becomes
bright to dark.
If operation is not as specified, replace the inner mirror.
